A Sensor In Every Pocket
A Sensor In Every Pocket
Scientists at the U.S. Department of Homeland Security are a phase closer to putting chemical detectors into the hands of everyone who wants them. Developers have finished demonstrating a miniaturized sensor that can fit into the now-omnipresent personal cell phone. Early testing shows promise for small, inexpensive technology, and over the next year or so project personnel plan to test its real-world application. The cell phone platform would enable crowd sourcing to reduce false positive readings, and it would support instant alerts that would send out timely notifications. The goal of developers is to improve public safety, enhance homeland security and ultimately save lives. In this next round of development, researchers with the program have to figure out how the network will support the technology and determine whether applications that seem strong in the laboratory will function in the field.
